Science
Mechanism of Action
This crosspolymer functions as a rheology modifier, acting as an absorbent, film former, and viscosity increasing agent. It effectively stabilizes oil-in-water emulsions, ensuring product homogeneity and extending cosmetic wear. By creating a protective barrier on the skin's surface, it aids in moisture retention, supporting the skin's natural barrier function.

Stability
This crosslinked polymer exhibits robust chemical stability, demonstrating insensitivity to solar ultraviolet (UV) degradation. It maintains integrity across a broad pH range of 5.5 to 12. However, formulators should be aware that high electrolyte (salt) concentrations may lead to an irreversible loss of viscosity in some acrylate crosspolymers.
Conflicts
- Avoid polymerization in benzene due to insufficient safety data.
- Potential loss of viscosity when exposed to high concentrations of electrolytes (salts).
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that crosslinked alkyl acrylates, including Lauryl Acrylate Crosspolymer, are safe in current cosmetic use practices and concentrations, provided they are not polymerized in benzene. Formulations must be designed to prevent skin irritation. While generally rated with low concerns for systemic toxicity by EWG, potential contamination by impurities such as methacrylic acid, acrylic acid, or benzene during manufacturing warrants consideration.
